Electrical

There is some kind of sensor behind the intake manifold. Directly in the middle of the car on the edge of the engine bay that is broken. It causes the car to spin over but not start. By wiggleing the word I can get it to start. Does anyone know what this part is and where I can get a replacement?

Just purchased a 1985 944 in good condition. The cruise control does not work. I do not have anything other than a Haynes repair manual (poor excuse for a repair manual), and am wondering if anyone has some information on troubleshooting. I have already checked the fuses, all seem to be good. I am assuming the electrical schematics in the Haynes manual are at least relevant. Is there some specific area I should be looking at. Before attempting to remove and replace all major subcomponents of the system, would like to be able to eliminate the components that test acceptable.

In the archves there was a question on the early 944 radio relay and the answer was its in the passenger footwell near the firewall. Do I removed the trim under the glove compartment to get to it? What does it look like? It isn't described in the manual or factory manual, just refers to it in the wiring diagrams.

Hello, I was only able to get normal speed from the wipers, as the high speed and intermittent no longer worked. I pulled the motor and checked it on the bench and it appeared to operate correctly, so I bought a new switch from Porsche and now the wiper fuse blows immediately when I use any of the switch settings- normal, intermittent or high speed. I’ve reinstalled the switch several times, being careful that it was all put together correctly, but the fuse blows every time.

I had to remove my steering wheel due to a broken weld on one of the spokes and have it repaired. I needed to replace the steering column bushing, so I removed the turn signal and wiper switches. After doing so, I noticed a thin metal part sticking out of the turn signal switch and it fell out of the switch.

I have a strange situation with my 84 944. While driving the turn signals stopped working. I get a green light on the dash but no blinking. When the hazards are turned on all four lights blink. I had my Porsche mechanic replace the turn signal switch, bulbs, and necessary fuses. The relay is fine. I took the car home and two days later the signals stopped again BUT the reverse lights stopped working. Hazard lights, brake lights still work.

I'm working on the sun roof of my 1985-1 944. I can make it work by jumpering the relays at the lifting motor, but not by the switch,should I have power at the switch? Talking to different people I'm told to check the relay.

I just swapped a 84 944 auto 3 speed to a manual and it started up once for a min. i shut it off and tried starting it and it wouldnt crank. I narrowed that down to a bad ground. But now that it cranks the engine wont start. The reference sensors are new. I re soldered the dme relay. I changed the igniton switch. I have 12 v to both sides of the coil. But when im cranking it over the test light dims alot. And right when im letting off the key it fires and then stops. Im confused.

One hot day after a short drive, after being parked for about an hour, the car would start but stumble and stall and sometimes rev up to 3000 and had no power. So far, I have checked the fuel pressure, replaced the throttle position sensor,checked the temperature sensor, replaced oxygen sensor, replaced the engine management computer, checked the spark plugs, wires,distributor cap and rotor with an engine analyzer hooked to the engine. Only cylinder 1 and 4 are getting a signal to spark.

The dash lighting in my 944 is dim to the point where I can't read the speedometer and most of the gauges at night. My local Porsche specialists replaced bulbs and the headlight control (which has the dash dimmer in it) but no luck. Is this really the best it can be? Is it possible to switch to brighter bulbs or LEDS for instance?
